Description

Technical Field

[0001] This invention belongs to the field of environmentally friendly material molding technology, specifically a manufacturing device and method for integrated curved surface components molded from renewable fibers. Background Technology

[0002] Curved surface components are structural parts with a three-dimensional curved surface profile. In furniture manufacturing, curved surface components are often used for assembling various furniture parts. During the production and processing of curved surface components, they are often hot-pressed using a hot press.

[0003] In existing technologies, hot-pressed components are often directly fed into the end container after demolding using a free-fall method. In batch continuous production scenarios, due to the impact of falling and the relative slippage between components, the components inside the container are in a non-directional, irregular, and disordered stacked state, and their spatial orientation is highly random.

[0004] Given that hot-pressed components generally need to be transferred to post-processing stages such as grinding and testing, the aforementioned messy stacking state will lead to the following technical defects: on the one hand, it is difficult for subsequent robotic arms or manual labor to quickly and accurately grasp individual components, which seriously delays the material flow between processes; on the other hand, operators cannot intuitively and accurately separate a specified number of components from the container, making it difficult to adapt to the needs of rhythmic and balanced production scheduling, which greatly limits the operating efficiency of production line automation.

[0015] A method for manufacturing an integral curved surface component molded from renewable fibers includes the following specific steps: S1. First, the agricultural straw fiber raw material is cut into segments with a length of 15–35 mm, then crushed by a crusher and passed through a 30–50 mm sieve to obtain pretreated fibers. The pretreated fibers are then dried to a moisture content of 6–12%. S3. Mixing and batching: The dried pretreated fibers are mixed with binders, fillers, and flow promoters in a mixer for 30–60 minutes at the following mass percentages: pretreated fibers: 70–95%, binders: 3–30%, fillers: 5–10%, flow promoters: 5–10%. S2. Add an appropriate amount of the mixture for component molding into the preheated lower mold cavity, and then use a hydraulic cylinder to drive the upper mold to descend, so that the upper mold approaches the lower mold to close the mold cavity for hot pressing. Hot pressing is performed for 3–8 minutes at a temperature of 120–220℃ and a pressure of 50–100Mpa. S3. After the component cools and forms, the upper mold moves upward away from the lower mold, the demolding rod rises, and the component is ejected from the cavity. When the lower end of the component is about to leave the cavity, the second transverse column moves laterally, so that the receiving rod passes through the inner contour of the ejected component. When the component is completely removed from the cavity, the component will be placed on the receiving rod with the top of the inner contour in contact with the receiving rod. Then, the push block rises, so that the push block is aligned with the upper edge of the component. The threaded block moves laterally, and the push block pushes the component on the receiving rod, so that the component moves towards the second transverse column until the component is in contact with the surface of the second transverse column. Whenever a component is formed, it will be placed on two receiving rods. The push block pushes multiple components to a mutually contacting state, so that multiple components are arranged in an orderly manner on the receiving rods. S4. Set the base at a suitable position on one side of the conveyor belt used for conveying components. The position of the tilting plate in the x, y, and z axis directions, according to the number of components to be picked up at one time, make the corresponding number of clamping blocks simultaneously align with multiple components. The clamping blocks on both sides move closer to each other to clamp the specified number of components at the same time. Then drive the components to rise and remove the components from the receiving rod. If the components need to be stacked, the tilting plates on both sides rotate 90 degrees, and the components are horizontal with the conveyor belt. By controlling the displacement of the tilting plates, multiple components are placed on the conveyor belt in a stacked state. S5. If it is necessary to lay multiple components equidistantly on the conveyor belt, changing the distance between adjacent sliders will change the corresponding component spacing, causing multiple worms to rotate simultaneously, and the clamping block to rotate 90 degrees under the transmission of the worm and worm wheel, so that multiple components are in a horizontal state. At this time, multiple components can be laid equidistantly on the conveyor belt.

[0016] The beneficial effects of this invention are as follows: 1. The manufacturing apparatus and method for an integrated curved surface component molded from renewable fibers, as described in this invention, utilizes a component collection auxiliary structure. Each time a component is formed, it is placed on two receiving rods, and a pusher pushes multiple components into a mutually adhering state, thus arranging them in an orderly manner on the receiving rods. This facilitates rapid and precise grasping of individual components by a robotic arm or manual labor, promoting the flow of components between processes. Furthermore, operators can intuitively and accurately separate a specified number of components, facilitating adaptation to rhythmic and balanced production scheduling requirements and significantly improving the operational efficiency of the automated production line.

[0017] 2. The manufacturing apparatus and method for an integrated curved surface component molded from renewable fiber described in this invention utilizes a component placement shape adjustment component. With the coordinated cooperation of multiple clamping blocks, a specified number of components can be removed from the receiving rod. Furthermore, the specified number of components can be placed on the conveyor belt in an overlapping or equidistant manner according to actual needs, in order to adapt to different subsequent processing requirements, resulting in high material transfer efficiency.

[0018] 3. The apparatus and method for manufacturing integrated curved surface components using renewable fiber molding as the main raw material, without the need to add plastic resin, can manufacture complex, high-strength, and environmentally friendly curved furniture components through a single molding process, realizing green manufacturing and efficient resource utilization.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please refer to Figures 1-10The present invention provides a technical solution: a manufacturing device for an integrated curved surface component molded from renewable fiber, comprising a base 1, a worktable 3 fixedly connected to one side of the upper end face of the base 1, a fixing rod 12 fixedly connected to each of the four corners of the upper end face of the worktable 3, a top plate 2 fixedly connected to the upper ends of the four fixing rods 12, and an upper mold 10 slidably mounted on the four fixing rods 12, a lower mold 9 fixedly connected to the upper end face of the worktable 3, a mixture being fed into the preheated cavity of the lower mold 9, and the upper mold 10 closing the cavity near the lower mold 9 for hot pressing, including a component demolding assembly; The component demolding assembly includes a demolding rod 13, which slides through the bottom of the cavity of the lower mold 9 and the upper end of the worktable 3. During hot pressing, the upper end of the demolding rod 13 is flush with the bottom of the cavity of the lower mold 9. The base 1 is equipped with a component collection auxiliary structure; The component collection auxiliary structure includes a lead screw guide module 2 6 set on one side of the upper end face of the base 1. The sliding output end of the lead screw guide module 2 6 is fixedly connected to a transverse column 2 7. Two receiving rods 8 for placing components are fixedly connected to one side of the upper end of the transverse column 2 7. The demolding rod 13 pushes the molded component out of the cavity. The receiving rods 8 move laterally and pass through the inner contour of the component, so that the component falls on the receiving rods 8.

[0024] In this embodiment, as Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, a cylinder 14 is fixedly connected to one side of the top of the inner cavity of the workbench 3, and the piston end of the cylinder 14 is fixedly connected to one end of the demolding rod 13.

[0025] A hydraulic cylinder 11 is fixedly connected to one side of the upper end face of the top plate 2, and the piston end of the hydraulic cylinder 11 is fixedly connected to one side of the top of the upper mold 10.

[0026] A component fitting auxiliary assembly is provided on the transverse column 27; The component bonding auxiliary component includes a push block 37, which is located between two receiving rods 8. The push block 37 moves laterally between the two receiving rods 8 to push the components on the receiving rods 8, so that multiple components bond with each other.

[0027] A slide rod 34 is fixedly connected to one side of the upper end of the transverse column 2 7. A threaded block 39 is slidably connected to the slide rod 34. A cylinder 36 is fixedly connected to the bottom of the threaded block 39. The piston end of the cylinder 36 is fixedly connected to the bottom of the push block 37. A threaded rod 2 35 is threadedly connected to one end of the threaded block 39. One end of the threaded rod 2 35 is rotatably mounted on the transverse column 2 7. A motor 4 38 is fixedly connected to one side of the upper end of the transverse column 2 7. The output end of the motor 4 38 is fixedly connected to one end of the threaded rod 2 35.

[0028] Specifically, in existing technologies, hot-pressed components are often directly fed into the end container after demolding using a free-fall method. In batch continuous production scenarios, due to the impact of falling and the relative slippage between components, the components inside the container are in a non-directional, irregular, and disordered stacking state, and their spatial orientation is highly random.

[0029] Given that hot-pressed components generally need to be transferred to post-processing stages such as grinding and testing, the aforementioned messy stacking state will lead to the following technical defects: on the one hand, it is difficult for subsequent robotic arms or manual labor to quickly and accurately grasp individual components, which seriously delays the material flow between processes; on the other hand, operators cannot intuitively and accurately separate a specified number of components from the container, making it difficult to adapt to the needs of rhythmic and balanced production scheduling, which greatly limits the operating efficiency of production line automation.

[0030] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: This method is applied to the hot pressing of U-shaped components in curved surfaces. First, an appropriate amount of the mixture for component forming is added to the preheated cavity of the lower mold 9. Then, the upper mold 10 is lowered by the hydraulic cylinder 11, so that the upper mold 10 approaches the lower mold 9 to close the mold cavity for hot pressing. Hot pressing is carried out for 3–8 minutes at a temperature of 120–220℃ and a pressure of 50–100 MPa.

[0031] After the component cools and solidifies, the upper mold 10 moves upward away from the lower mold 9. Then, cylinder 14 drives the demolding rod 13 to rise, ejecting the component from the cavity. As the lower end of the component is about to leave the cavity, the lead screw guide module 26 drives the transverse column 2 7 to move laterally, so that the receiving rod 8 passes through the inner contour of the ejected component. When the component is completely removed from the cavity, the component will be placed on the receiving rod 8 with the top of the inner contour in contact with the receiving rod 8. Then, the receiving rod 8 moves away from the lower mold 9. Then, cylinder 36 drives the push block 37 to rise, so that the push block 37 is aligned with the upper edge of the component. Then, motor 4 38 drives the threaded rod 2 35 to rotate, so that the threaded block 39 moves laterally. The push block 37 pushes the component on the receiving rod 8, so that the component moves towards the transverse column 2 7 until the component is in contact with the surface of the transverse column 2 7.

[0032] Then, the above operation is repeated. Each time a component is formed, it is placed on two receiving rods 8, and the pusher block 37 pushes multiple components into a mutually adhering state, thus arranging them orderly on the receiving rods 8. This allows subsequent robotic arms or manual labor to quickly and accurately grasp individual components, facilitating the flow of components between processes. Furthermore, operators can intuitively and accurately separate a specified number of components, making it easier to adapt to the needs of rhythmic and balanced production scheduling, significantly improving the operational efficiency of the production line automation.

[0033] In this embodiment, as Figure 1 , Figures 7-10 As shown, a component placement shape adjustment assembly is provided on the base 1; The component placement and adjustment assembly includes pillars 19 symmetrically distributed on both sides of the base 1. A flip plate 21 is rotatably mounted on one end of each pillar 19. A guide frame 22 is fixedly connected to one end of the flip plate 21. Multiple sliders 26 are equidistantly mounted on the guide frame 22 along the horizontal direction. The rightmost slider 26 is fixedly connected to the guide frame 22, while the other sliders 26 are slidably connected to the guide frame 22. A rotating shaft 27 is rotatably mounted on one end of each slider 26, and a clamping block 25 is fixedly connected to one end of the rotating shaft 27.

[0034] The bottom of the leftmost and rightmost sliders 26 are rotatably equipped with connecting rod 31, and the bottom of the other sliders 26 are rotatably equipped with connecting rod 32. One end of connecting rod 31 is rotatably connected to one end of connecting rod 32, and the ends of two adjacent connecting rods 32 are rotatably connected. One end of the leftmost slider 26 is threadedly connected to a threaded rod 33. Both ends of the threaded rod 33 are rotatably set in the groove of the guide frame 22. One end of the flip plate 21 is fixedly connected to a motor 24, and the output end of the motor 24 is fixedly connected to one end of the threaded rod 33.

[0035] A worm gear 28 is fixedly sleeved on the end of the rotating shaft 27 away from the clamping block 25. A worm 30 is rotatably mounted on one side of the slider 26. The worm 30 meshes with the worm gear 28. A protruding rod 29 is rotatably mounted on one end of the flip plate 21. The inner cavity of the worm 30 is provided with a keyway that matches the protrusion on the surface of the protruding rod 29. Multiple worms 30 are slidably inserted into the protruding rod 29 through the keyway. A second motor 23 is fixedly connected to one end of the flip plate 21. The output end of the second motor 23 is fixedly connected to one end of the protruding rod 29.

[0036] Two sets of lead screw guide rail modules 15 are symmetrically arranged on the upper surface of the base 1. A transverse column 4 is fixedly connected to the sliding output end of the lead screw guide rail module 15. A lead screw guide rail module 3 15 is arranged on one side of the transverse column 4. A lifting plate 16 is fixedly connected to the sliding output end of the lead screw guide rail module 3 15. Two guide rods 18 are slidably connected on the lifting plate 16. One end of the guide rod 18 is fixedly connected to one end face of the support column 19. A cylinder 2 17 is fixedly connected to one side of the lifting plate 16. The piston end of the cylinder 2 17 is fixedly connected to one side of the support column 19. A motor 20 is fixedly connected to one end of the support column 19. The output end of the motor 20 is fixedly connected to one end of the flip plate 21.

[0037] Specifically, in the above embodiments, although the receiving rod 8 can be used to place components for retrieval, in some cases, it is necessary to place a specified number of components on a conveyor belt in a stacked or equidistant manner according to the total number of components, and then transport the components to a designated location for processing to meet different processing needs. If workers manually remove the components one by one and place them on the conveyor belt, it will result in high labor intensity and make it difficult to accurately control the spacing between adjacent components laid flat. If robotic arms pick them up one by one, it will result in a large number of reciprocating gripping operations, thus affecting the material transfer efficiency. If the number of robotic arms is increased to increase the amount that can be picked up at one time, it will not only result in high costs and cumbersome operation, but also make it easy for the robotic arms to collide with each other due to alternating operations, which will also affect the material transfer efficiency.

[0038] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: The base 1 is positioned at a suitable location on one side of the conveyor belt used for conveying components. The position of the tilting plate 21 in the x, y, and z axes can be adjusted via the lead screw guide module 1 5, lead screw guide module 3 15, and cylinder 2 17. Based on the number of components to be picked up at one time, the corresponding number of clamping blocks 25 are simultaneously aligned with multiple components. Then, cylinder 2 17 drives the tilting plate 21 to move laterally, bringing the clamping blocks 25 on both sides closer together to clamp the specified number of components simultaneously. Subsequently, the components are driven upward to remove them from the receiving rod 8. If the components need to be stacked, the motors 1 20 on both sides simultaneously drive the tilting plates 21 on both sides to rotate 90 degrees, making the components horizontal with the conveyor belt. Multiple components can then be placed on the conveyor belt in a stacked state by controlling the displacement of the tilting plate 21.

[0039] If multiple components need to be laid equidistantly on the conveyor belt, the leftmost slider 26 can slide on the guide frame 22 by rotating the threaded rod 33 driven by motor 24. Simultaneously, under the transmission cooperation of connecting rod 31 and connecting rod 32, multiple sliders 26 slide on the guide frame 22 at the same time, thus changing the distance between adjacent sliders 26, and the corresponding component spacing also changes. Furthermore, when the slider 26 slides on the guide frame 22, the worm 30 also slides on the convex rod 29. Then, by rotating the convex rod 29 driven by motor 23, multiple worms 30 rotate simultaneously. Under the transmission of the worm 30 and worm wheel 28, the clamping block 25 rotates 90 degrees, so that multiple components are in a horizontal state. At this time, multiple components can be laid equidistantly on the conveyor belt. Thus, through the above adjustment operation, a specified number of components can be removed from the receiving rod 8 at a time, and a specified number of components can be placed on the conveyor belt in an overlapping or equidistant manner according to actual needs to adapt to different subsequent processing requirements.

[0040] A method for manufacturing an integral curved surface component molded from renewable fibers includes the following specific steps: S1. First, cut the agricultural straw fiber raw material into segments with a length of 15–35 mm, then crush it using a crusher and pass it through a 30–50 mm sieve to obtain pretreated fibers. Dry the pretreated fibers to a moisture content of 6–12%. S3. Mix the ingredients: Mix the dried pretreated fibers with binders, fillers, and flow promoters in a mixer for 30–60 minutes according to the following mass percentages: pretreated fibers: 70–95%, binders: 3–30%, fillers: 5–10%, flow promoters: 5–10%. S2. Add an appropriate amount of the mixture for component molding into the preheated lower mold 9 cavity, and then use the hydraulic cylinder 11 to drive the upper mold 10 down, so that the upper mold 10 approaches the lower mold 9 to close the mold cavity for hot pressing. Hot pressing is performed for 3–8 minutes under the conditions of temperature 120–220℃ and pressure 50–100Mpa. S3. After the component cools and forms, the upper mold 10 moves upward away from the lower mold 9, the demolding rod 13 rises, and the component is ejected from the cavity. When the lower end of the component is about to leave the cavity, the transverse column 7 moves laterally, so that the receiving rod 8 passes through the inner contour of the ejected component. When the component is completely removed from the cavity, the component will be placed on the receiving rod 8 with the top of the inner contour in contact with the receiving rod 8. Then, the push block 37 rises, so that the push block 37 is aligned with the upper edge of the component. The threaded block 39 moves laterally, and the push block 37 pushes the component on the receiving rod 8, so that the component moves towards the transverse column 7 until the component is in contact with the surface of the transverse column 7. Whenever a component is formed, it will be placed on two receiving rods 8. The push block 37 pushes multiple components to a mutually contacting state, so that multiple components are arranged in an orderly manner on the receiving rod 8. S4. Set the base 1 at a suitable position on one side of the conveyor belt used for conveying components. The position of the flipping plate 21 in the x, y, and z axis directions, according to the number of components to be picked up at one time, make the corresponding number of clamping blocks 25 simultaneously align with multiple components. The clamping blocks 25 on both sides move closer to each other, clamping the specified number of components at the same time. Then drive the components to rise and remove the components from the receiving rod 8. If the components need to be stacked, the flipping plates 21 on both sides rotate 90 degrees, and the components are horizontal with the conveyor belt. By controlling the displacement of the flipping plate 21, multiple components are placed on the conveyor belt in a stacked state. S5. If it is necessary to lay multiple components equidistantly on the conveyor belt, the distance between adjacent sliders 26 is changed, and the corresponding component spacing also changes, causing multiple worm gears 30 to rotate simultaneously, and under the transmission of the worm gears 30 and worm wheel 28, the clamping block 25 is rotated 90 degrees, so that multiple components are in a horizontal state. At this time, multiple components can be laid equidistantly on the conveyor belt.

10. A method for manufacturing an integral curved surface component molded from renewable fibers, characterized in that, Manufacturing using the manufacturing apparatus according to any one of claims 1-9 includes the following specific steps: S1. First, the agricultural straw fiber raw material is cut into segments with a length of 15–35 mm, then crushed by a crusher and passed through a 30–50 mm sieve to obtain pretreated fibers. The pretreated fibers are then dried to a moisture content of 6–12%. S3. Mixing and batching: The dried pretreated fibers are mixed with binders, fillers, and flow promoters in a mixer for 30–60 minutes at the following mass percentages: pretreated fibers: 70–95%, binders: 3–30%, fillers: 5–10%, flow promoters: 5–10%. S2. Add an appropriate amount of the mixture for component molding into the preheated lower mold (9) cavity, and then use the hydraulic cylinder (11) to drive the upper mold (10) to descend, so that the upper mold (10) approaches the lower mold (9) to close the mold cavity for hot pressing. Hot pressing is performed for 3–8 minutes under the conditions of temperature 120–220℃ and pressure 50–100Mpa. S3. After the component is cooled and formed, the upper mold (10) moves upward away from the lower mold (9), the demolding rod (13) rises and pushes the component out of the cavity. When the lower end of the component is about to leave the cavity, the transverse column two (7) moves laterally so that the receiving rod (8) passes through the inner contour of the ejected component. When the component is completely removed from the cavity, the component will be placed on the receiving rod (8) with the top of the inner contour in contact with the receiving rod (8). Then, the push block (37) rises so that the push block (37) is aligned with the upper edge of the component. The threaded block (39) moves laterally and pushes the component on the receiving rod (8) through the push block (37) so that the component moves towards the transverse column two (7) until the component is in contact with the surface of the transverse column two (7). Whenever a component is formed, it will be placed on two receiving rods (8). The push block (37) pushes multiple components to a mutually contacting state so that multiple components can be arranged in an orderly manner on the receiving rod (8). S4. Set the base (1) at a suitable position on one side of the conveyor belt used for conveying components. The position of the flip plate (21) in the x, y, z axis directions, according to the number of components to be taken at one time, make the corresponding number of clamps (25) simultaneously align with multiple components. The clamps (25) on both sides approach each other and clamp the specified number of components at the same time. Then drive the components to rise and remove the components from the receiving rod (8). If the components need to be stacked, the flip plates (21) on both sides rotate 90 degrees and the components are horizontal with the conveyor belt. By controlling the displacement of the flip plate (21), multiple components are placed on the conveyor belt in a stacked state. S5. If it is necessary to lay multiple components at equal intervals on the conveyor belt, change the distance between adjacent sliders (26), and the corresponding component spacing will also change, so that multiple worms (30) rotate at the same time, and under the transmission of worms (30) and worm wheels (28), the clamp (25) is rotated ninety degrees, so that multiple components are in a horizontal state. At this time, multiple components can be laid at equal intervals on the conveyor belt.
